Typical Applications

The HMC545A / HMC545AE is ideal for:

• Cellular/3G Infrastructure

• Private Mobile Radio Handsets

• WLAN, WiMAX & WiBro

• Automotive Telematics

• Test Equipment

The HMC545A and HMC545AE are low-cost SPDT

switches in 6-lead SOT26 plastic packages for use

in general switching applications which require

very low insertion loss and very small size. With

0.25 dB typical loss, these devices can control

signals from DC to 3.0 GHz and are especially suited

for IF and RF applications including Cellular/3G,

ISM, automotive and portables. The design provides

exceptional insertion loss performance, ideal for filter

and receiver switching. RF1 and RF2 are reflective

shorts when “Off”. The two control voltages require a

minimal amount of DC current and offer compatibility

with CMOS and some TTL logic families.
